Mandrel Bends Headers And Exhaust

Our mandrel bends are available in mild steel, 304 stainless steel and 321 stainless steel. We maintain large inventory of mandrel bends that are most common in the racing industry.

What makes mandrel bent tubing different from standard bent tubing?

The end result is a bend that retains its shape and diameter throughout its entire bend. For performance purposes, this is an essential component in keeping the exhaust velocity and flow to optimum levels. Standard bends restrict exhaust flow by a reduction in the tube diameter in the bent areas.

Mandrel bending is performed by a mandrel that is drawn through the inside of the tube during the bending process. This maintains the dimensional and tube shape integrity.
